Plan for Oracle RAC

Before starting, verify system requirements.
The default tablespace size for Oracle RAC may need to be set to 1024MB with autoextend turned on for database transfer to be successful.

Application Description DB name Space required
WebSphere Portal User customization, such as pages, and user profile and login information. reldb
commdb
custdb Depends on the number of users and portal objects, such as pages and portlets.
Personalization, WCM Documents, personalization rules, personalization campaigns, and document library configuration information. jcrdb Depends on the number and size of Personalization rules and campaigns, and the number and size of items and elements created in Web Content Manager.
Feedback Information logged by the Web site for analysis of site activity and generating reports. fdbkdb Depends on the amount of traffic to the site. The amount of data logged per login-enabled page can vary.
LikeMinds Recommendations to be displayed to users when their interactions with the Web site have been analyzed and predictions generated. lmdb Depends on the amount of traffic to the site.

The architecture allows each of the following users to exist in the same database. All table spaces are approximately 2.8 GB by default. The size increases with the use of Java Content Repository.
